PlTLESS WEIGHING-SCALE.

No. 842, 11 8. Specification of Letters Patent. Patented Jan 29, 1907.

Application filed January 16, 1906. Serial No. 296.259.

To (1,7 7. w/tom, it put concern/.-

e it known that I, DARIUS M. OROUTT, a citizen of the United States, residing at Kansas City, in the county of lVyandotte and State of Kansas, have invented certain new and useful Improvements in Pitless VVeighing-Scales, of which the following is a specification.

This invention relates to weighing-scales, and more especially to that class known as pitless weighing-scales; and my object is to produce a scale of this character provided with a combination cement and metal frame.

A further object is to produce a scale of this character in which the bearings for the platform portion of the scale are adjustable longitudinally and laterally to accommodate any inaccuracy in the erection of the scale or which occurs after it has been erected.

A further object is to produce a scale of this character in which the scale-beam lever is adjustable transversely of the platform to accommodate the position of the rocker shaft arms in order to insure accuracy in the weighing operation.

With these and other objects in view, as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a plan view of a portion of a scale, with the platform omitted, embodyin my invention. Fig. 2 is an enlarged section taken on the line II II of Fig. 1. Fig. 3 is an enlarged section taken on the line III III of Fig. 1. Fig. 4 is an enlarged section taken on the line IV IV of Fig. 1, but with one cf the stirrups partly in section to disclose features of construction. hereina described. Fig. 5 is an enlarged vertical section taken on the line V V of Fig. 1. Fig. 6 is a section taken on the line V1 VI of Fig. 4. Fig. 7 is a detail perspective view of one of the cornerbrackets of the frame. Fig. 8 is a sectional perspective view of the bracket. for the scalebeam lever.

Referring to the drawings in detail, where like reference characters indicate corresponding parts, 1 indicates cement beds or foundations for each-corner of the frame, one bed only being disclosed. Secured upon each cement-bed is a corner-bracket constructed respectively, at its outer side and end with vertical walls 3 and 4. all 3 is paralleled by .1. outer wall 5, connected to wall 3 by a cross-piece or rib 6. l Vall 4 is paralleled by an. outer wall 7, connected to wall 4 by a cross-piece or rib t3.

9 indicates an angular cement wall of the same height as and extending from crosspiece or rib 6 to cross-piece or rib 8 and snugly embraced by the contiguous portions of th inner and outer walls 3 4 and 5 7, and 10 indicates cement end walls, one only appearing, extending from the cross-piece or rib 8 to the corresponding cross-piece or rib of the corner-bracket (not shown) at the same end of the frame. 11 indicates cement side walls extending from cross-piece or rib 6 of one corner-bracket to the cross-piece or rib of the corner-bracket (not shown) at the opposite end of the frame. The cornerwalls 9 and those portions of walls 10 and 11 between walls 4 and 7 and 3 and 5, respectively, upon and practically form upward extensions of the underlying portions of the beds 1, which, it will be noted, are wider than said walls to wholly underlie the bedplates One of said side cement walls is in two sections, terminating a suitable distance apart, as shown in Fig. 1, the sections of said wall being connected by a bracket hereinajfi r eescribed. All of said cement walls are pselhrably of the same height as the metal walls 3 and 5, and, if desired, said cement walls may extend downward into the ground to lend additional stability and rigidity to the frame, though they are not so shown, as the depth of said walls forms no part of the invention.

The inner wall 3 of each corner-bracket is preferahly provided with a pair of perforated ltosses 12 13, which are disposed in alinement with the perforated heads of stai'idards 14. and 15, respectively, rising from the bed-plate 2, the standard 15 being of senii-arthed form and having its major portion disposed some distance inward of its perforatrd head for a purpose which hereinafter appears.

16 indicates pivot bolts connecting bosses 12 and 13 with the heads of standards 14 and 1.5 and sea ured at their ends in the perforations of said bosses and standards.

A swinging hanger for each corner-bracket comprises a pair of swing-bars 17, pivotally suspended from bolts 16 and pivotally en-- as follows: 2 indicates a bed-plate provided,

gaging the bifurcated ends of a horizontal IIO link 18, having its upper surface corrugated transversely, as at 1.9. indicates a bearing-block having its lower side likewise corrugated and engaging the corrugated upper surface of link 18, said block being preferably shorter than the. corrugated portion. of the link, so as to be adjustable longitudinally thereon. The width of said link and block is such as to also permit of a limited lateral ad justment of the blork on. the link, and the block is provided in its upper side with a transverse bearing-eavity 21 to receive the knife-bearing 22, projecting outward from the arm 23 of the rock-shaft 24, one rockershaft only appearing, though of course there will be another contiguous to and parallel with the other end wall of the frame. Each rock-shaft is likewise provided a suitable dis-- tance from each end with an arm 25, pro jecting in the opposite direction from arm and equipped at its upper side with a trans-- verse knife-bearing 26.

27 indicates longitudinal beams, n'eferably I-beams, in longitudinal alii'iement witl: the alined arms of the rocker-shafts, one I-beam only being shown, and secured to each end of each I-lxcam are a pair of plates 28, provided with arms 29, of such configuration as to overhang and project outwardly beyond. the rocker-shafts, as shown most clearly in Figs. 1 and 2, and formed integral by preference with the inner sides of arms 29 inward of the coi'itiguous madam-shaft air a pair of longitudinalribs 30, having theirlower sides transversely corrugated, as at 31.

32 indicates a bearing-block bridging the space between companion arms 29 and. hav-- ing its upper side transversely corrugated aml engaging the tcrrugatioi'is of ribs 3t), the lower side of said bearingblock being con-- caved, as at 33, and. resting upon the knifebearing 26 of rocker-shaft arms 25, said bear-- ing-blocks 32 being longitudinally adjustable on the bearing-ribs 3] The platform. (indicated at 34:) is preferably constructed of planks extending transversely of the scale and secured in. the usual or any preferred manner to the I-beams and the arms 29 projecting beyond the same.

From the foregoing it will be apparent by reference to the drawings that the platform may vibrate longitudinally of the s4 ale in the usual manner, the hangers swinging to permjit this vibration without causing the links 18 thereof to assume angular positions with respect to the base-plates, and therefore without imposing undue resistance to the vibratory movement of the platform.

L1G platform, furthermore ,has the necessary vertical or up-and-down movement without causing it to assume an angular position with respect to the base-plates, the rockershaft bearing knives 22, fulcruming on tho bearing-blocks 20, the knife-bearing 26 and bearingblocks 32 rising and falling with the platform and operating together with the minimum of frietioi'i, as will be readily understood.

The bracket which forms the fulcrum of the scale-beam lever is disposed transversely and consists of an end wall 35, side walls 36 projecting outwardly from the ends of wall 35 and diverging outwardly slightly by preferenee and terminating at their outer ends in substaijitially Lshaped portions 37, the bases of said portions being alined with side walls of the corner-brackets and the heads with the outer side walls 5 of the corner-brackets, the contiguous ends of the cement side-wall sections 11 fitting between said bases and heads and abutting against the stem portions connecting said bases and heads, as shown clearly in Fig. l

The bracket is provided integrally at the junction of walls 35 and 36 with ribs 38, extending traa'isversely of the scale and corrugated longitudii'ially of the scale at their upper sides, as at 35), and bridging the space between and supported by paid ribs is a bearing-block -.t(), having i lower surface corrugated, as at 4]., to engage the corrugatioi'is 39, the block 40 being adjustable on ribs transversely of the scale and also having its upper side formed. with a behating-cavity 42, engaged by the depending knife-bearing 43, secured to the inner end of the scale-b am lover 414-, which lever extends longitudinally of its su pporting-bracket and 'n'ojectsbeyond the sections of wall 11, its opposite end being connected in the usual or any preferred manner to the scalabeam. (Not shown.) The lever inward of the side wall beyond whichit 'n'ojeets is provided with a transverse opening for gaging purposes in the shop work.

At opposite sides of said. opening the lever is provided with outwardly-projecting lugs 4.6, n'ovided with upwardly-projectin conepointed bearing-pii'is 4'7, engaging cavities 48 in the upper ends of stirrups at), the lower portions of said stirrups being provided with cavities 50, engaged by depending conepointed bearing-pins 51 of arms 52, secured rigidly to the rocker-shafts in any suitable manner and projecting through large openings .53 in the side walls 36 of the bracket forn'iing the fulcrum or support of said lever.

Should the arms 57 through. inz'tccuracy of coi'istruction or of fit have their inner or contiguous ends disposed outward or inward of the vertical plane which they scientifically should occupy, the large openings 53 will accommodate them, and the bearing-block 40 of lever 44 will be adjustable transwarsely of the scale on ribs 38 to accon'lmodate the positions of said arms, as will be readily under stood, the moven'ient of the rocker-shafts being transmitted to lever 44. through the instrumentality of arms 52 in the usual manner, lateral and. longitudinal vilnatorv movement of the platform independent of the leseams ver 44 being accommodated by transverse swinging movement of the stirrups, as is customary in this class of scales.

Among the special advantages of a scale of this character is compactness for shipment, as the heavy and cumbersome side and end channel-irons usually forming an 'importai'ri part of a scale of this character are dispensed with. The cement side and end walls, corner portions 9, and foundation for the cornerbrackets can be erected easily and cheaply with the aid of any suitable false work or forms, (not shown) it being understood that a pitless scale having its frame composed of the usual channel-iron sides and ends is erected upon a cement foundation. and that conse quently the production of the cement walls as contemplated herein. can be accomplished without necessitating anything but a larger quantity of the material for the erection of such walls and the building of the false work to a higher plane than where the cement forms the foundation only.

From the above description it will be apparent that I have produced a scale embodying the features of advantage enumerated as desirable in the statement of invention. and which obviously may be modified in minor particulars without departing from the spirit and scope of the appended claims.

Having thus described the lllVGll'tlOIl, what I claim as new, and desire to secure by Letters Patent, is
